Cypress Lithium Claystone/Brine Projects in Nevada

Highlights of Cypress Lithium Projects in Nevada The discovered lithium mineralization at Cypress’ Dean and Glory Projects is ideally

located within a basin that hosts the only significant lithium production in the UnitedStates.

Cypress' Clayton Valley Projects are in close proximity to essential mininginfrastructure.

The consistent nature of the currently known lithium mineralization at Cypress’ Deanand Glory Projects is highly encouraging for both the potential size and potentialresource extraction methodologies.

The data to date outlines an area seven kilometers-long at Cypress’ Dean and GloryProjects which presents a strong starting point for planning a resource estimation.

Cypress Development believes this discovery has the scale to significantly impact thefuture production of lithium in the Clayton Valley.

Cypress also believes this new lithium source could well represent a long-term,reliable supply of lithium given the location, known size, chemistry and geometry ofthe discovery.

Additional drilling should allow the Company to contemplate a sizable maiden lithiumresource at Cypress’ Clayton Valley Project.

Lithium-Rich Claystone at Dean & Glory Projects

Dean Project Surface Claystone Sample Map

Maximum value in Dean claystone was3,730 ppm lithium (1.98% Li2CO3equivalent);

8 Dean samples assayed greater than2000 ppm lithium (>1.06% Li2CO3equivalent);

Glory Project Surface Claystone Sample

Map

Maximum lithium in claystone at Glorywas 3,830 ppm lithium (2.04% Li2CO3equivalent);

Extended Glory corridor of high lithium to3 kilometers-long;

9 Glory samples contained more than2,000 ppm lithium (>1.06% Li2CO3equivalent);

71 Glory samples contained more than1,000 ppm lithium (>0.53% Li2CO3equivalent); and

Anomalous boron (B) and potassium (K)trends that correlate with the high lithium(Li) values.

Glory Project Surface Claystone Lithium Results Glory sampling returned the highest reported assay result for lithium in sediments (3830 ppm Li)

known by the Company to be publicly reported in Clayton Valley, Nevada.

Extensive sampling at Glory Project show a 3 kilometer-long zone of north-south strike of lithium-rich outcropping claystone that assay approximately 1,500 ppm Li (0.80% Li2CO3) on average.

Results suggest a strong possibility of continuous mineralized volume of a highly leachablelithium-rich claystone at surface on the Cypress Glory Project in a position immediately southeastof the Albemarle Silver Peak Mine.

Permit in place to drill a number of holes targeted to provide initial subsurface data and assaysunder the wide zone of strongly mineralized claystone outcrops.

This drilling should allow Cypress to begin to estimate size, lithium (Li) grade and tonnage in theclaystone at the Company's Glory Project.

Glory Project Lithium Brine Potential Cypress has reviewed the seismic data in Pure Energy Minerals NI 43-101 Technical Report titled

"Inferred Resource Estimate for Lithium, Clayton Valley South Project", dated July 17, 2015.

The Pure Energy seismic data appears to indicate favorable lithium brine targets along the westernand west central portions of Cypress' Glory Property.

Future drilling at Cypress' Glory Project will include hole locations targeting potential lithium-rich brineswithin the Main Ash Aquifer projected to underlie the west and west-central portions of Glory Project.

The Main Ash Aquifer is the primary target of these holes. Cypress expects to intersect this zone at150 to 300 meters below surface.

Additional deeper targets will also be tested including the potential presence of a coarse gravel aquifernear the base of the basin fill evaporite sequence.

Solubility Lab Testing on Glory & Dean Claystone

Solubility lab testing on 7 kilometers of claystone samples from across Cypress' Glory and DeanProperties have shown an impressive average of 35% Li recovery using a water leach and 95% Lirecovery using a dilute Aqua Regia leach process.

The data shows that a readily soluble non-hectorite mineral form of lithium-rich claystone exist atsurface covering an area 7 kilometers-long across Cypress' Glory and Dean Clayton Valley Projects.

The goal of this work is to substantiate the potential to produce lithium directly from the mineralizedclaystone with a low cost and environmentally friendly approach without the need for roasting or othercostly mining and complex treatments.

Cypress is proceeding with additional leach studies with the Glory and Dean claystone to determinethe amount of lithium extraction possible from the claystone and to provide further data on thefeasibility of a large scale leach extraction method of lithium from the abundant mineralized claystone.

Claystone Water Leach & Synthetic Li Brine Study Dean water leach assays show strong extraction of lithium with very low extraction of magnesium

and calcium. The water and soluble element "synthetic brine" produced has very similarchemistry to that of reported chemistry of production brines from the Clayton Valley Mine and tobrines reported by Pure Energy Minerals.

Table below compares chemistry of the Dean "synthetic brine" produced to actual production andresource brines in the Clayton Valley. Note that the lithium value for the water leach solution fromthe Dean claystone is more than double that of the Pure Energy brine and is four times that ofthe Albemarle production brine.

Water Leach Synthetic Lithium Brine Conclusions It appears that a lithium bearing mineral solution, that is chemically similar to the production

and resource brines of the Clayton Valley, can be produced by the leaching of surfaceclaystone in water.

Comparison of ratios with other important elements also shows the Dean "Synthetic Brine"compares favorably with basin production brines.

The data provides further strong support for the idea that the production brines of the basin arebeing continuously recharged by leaching of lithium and other elements from the uplifted andexposed former lake basin sediments that outcrop in a wide belt along the east margin of theClayton Valley.

This recharge mechanism strongly supports the importance of the outcropping and buriedclaystone as a very significant lithium source rock.

Cypress’ chemistry work-up shows how rain water and underground aquifers would extractlithium and sodium from the mineralized basin sediments at much higher rates than theextraction of magnesium and calcium.

Potential for existence of mineral brines under and immediately adjacent to the exposed belt oflithium rich rocks is high as the water flow pathways for the recharge system are likely to bevertical as well as horizontal.

Going Forward

Cypress is proceeding with additional leach studies with the Dean and Gory core to determinethe amount of lithium extraction possible from the Dean and Glory claystone.

The goal of this work is to substantiate the potential to produce lithium directly from the highlymineralized claystone with a low cost and environmentally friendly approach without the needfor roasting or other costly mining and complex treatments.

Additional drilling should allow Cypress to contemplate a sizable maiden lithium resource at theCompany’s Clayton Valley Projects.

Clayton Valley Location & Infrastructure

Well maintained state highways connect Silver Peak to the main road network in Nevada.

Nevada has fostered a thriving mining industry with associated development expertise, construction and operations services and a mature regulatory environment.

Single best mining jurisdiction in the U.S. and ranked 3rd globally by the respected “Fraser Institute’s annual Survey of Mining Countries”.

Graded and maintained gravel roads link Silver Peak to the southern half of Clayton Valley.

Nearest rail system is in Hawthorne, Nevada, approximately 90 miles by road.

Public use airport in Tonopah with two runways.

Electrical connection is possible at the sub-station in Silver Peak.

Water supply is currently served by the Silver Peak municipal water supply.

Lithium Timing

The energy storage revolution is generating high demand for lithium, with analysts forecastingdemand increases for the product (Li) in the near future.

Battery giants are scaling up lithium-ion production with mega-factories and areactively acquiring the raw material through off take agreements.

Companies already producing lithium are attempting to increase production.

Rockwood Holdings was purchased by Albemarle Corporation (NYSE: ALB) in 2014 for $6.2billion USD. This purchase included the Silver Peak Lithium Mine located in Clayton Valley,Nevada.

Tesla Motors is building a $5 billion battery gigafactory outside Reno, Nevada. A large amountof the supply of lithium will have to come from Nevada production. Tesla received major statetax incentives ($1.3 billion over the next 10 years for Tesla).

Electric vehicles and energy storage has become a huge demand driver for the increasedproduction in Clayton Valley and for the exploration and discovery of more lithium deposits inNevada.

Lithium Uses The most important use of lithium is in rechargeable batteries for mobile phones, laptops,

digital cameras and electric vehicles. Lithium is also used in some non-rechargeable batteriesfor things like heart pacemakers, toys and clocks.

Lithium is the most reactive metal known, also the lightest, with an atomic number of 3. Usedin batteries, lithium provides much better energy per volume ratio or energy density than anordinary alkaline battery or other common rechargeable battery such as a nickel-metalhydride. This is in part because lithium is the third-smallest element after hydrogen andhelium, and thus a lithium ion can carry a positive charge in a very small amount of space.Lithium-ion batteries can be recharged by running the anode and cathode reactions in reverseand the ability to be recharged many times over without much loss of capacity is anothermajor advantage of the lithium-ion battery.

Lithium metal is made into alloys with aluminium and magnesium, improving their strengthand making them lighter. A magnesium-lithium alloy is used for armour plating. Aluminium-lithium alloys are used in aircraft, bicycle frames and high-speed trains.

Lithium oxide is used in special glasses and glass ceramics. Lithium chloride is one of themost hygroscopic materials known, and is used in air conditioning and industrial dryingsystems (as is lithium bromide). Lithium stearate is used as an all-purpose and high-temperature lubricant. Lithium carbonate is used in drugs to treat manic depression, althoughits action on the brain is still not fully understood. Lithium hydride is used as a means ofstoring hydrogen for use as a fuel.
